mam/2o R'SCHEREP United States Patent US. Cl. 182-407 4 Claims ABSTRACTOF THE DISCLOSURE A safety device for ladders that prevents the dangerof a ladder slipping when in use. This device is equipped with acollapsible frame portion having a U-shaped tubular member at the basewhich is closed off by a U-shaped channel member against which thebottom of the ladder may rest, a second U-shaped member is inverted andpivotably connected to the bottom U-shaped member and resting the lowerportion of the ladder when the ladder is placed against a wall, andchain members secured to the structure of the device to prevent theover-extending of the U-shaped member on the underside of the ladder atits lower portion.

This invention relates to supporting devices and more particularly to asupporting device for ladders.

It is therefore the main purpose of this invention to provide a laddersafety support which consists of a porable, folded up frame, the framehaving a channel member at its base and an upright member at the otherend of the base, forming a protective frame which will prevent theslipping of the bottom of the ladder.

Another object of this invention is to provide a ladder safety supportwhich is simple in construction and principle and is light in weight sothat it may be carried easily.

A further object of this invention is to provide a support for ladderswhich shifts the point of normal slippage at the bottom of the ladder toan upper portion at which an upright member of the device will preventfurther movement of the ladder.

Other objects of the present invention are to provide a ladder safetysupport which is simple in design, inexpensive to manufacture, rugged inconstruction, easy to use and etficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIGURE 1 is a perspective view of the present invention showing theladder in phantom lines;

FIGURE 2 is an enlarged cross-sectional view taken along the lines 22 ofFIGURE 1; and

FIGURE 3 is a side view of the invention showing the ladder in positionagainst a wall.

According to the present invention, a safety ladder support is providedwith a base tubular U-shaped member 11, the open end of which is securedin a suitable manner within a length of U-shaped channel member 12. Anupright U-shaped tubular member 113 is secured at its open end by boltto the inner side of tubular member 11 and is thus pivotable about thebolt 14. A clevis bolt 15 is secured to the side of member 13 and has achain 16 secured to it. The other end of chain 16 is secured at any oneof its lower links to hooks 17 which are secured to and extending fromend walls 18 of channel member 12. The ladder 19 when in position restsupon the upright member 13 near its lower extremity and the legs 20 abutwith channel member 12 when ladder '19 is placed against wall 21. Inuse, when ladder 19 has sufiicient weight in the area upwards of themember portion of member 13, it may tend to slide away from wall 21,however, the weight instead is directed toward member 12, which forms afiat stabilizing support to prevent slippage.

It shall be noted that the free ends of chain 16 allow for variousadjustments of the length by placing any one of the lengths upon thehook 17 of channel member 12.

It shall further be noted that the tubular member 11 in conjunction withchannel member 12 form a maximum of frictional gripping of the ground inorder to prevent ladder 19 from slipping.

While various changes may be made in the detailed construction, it isunderstood that such changes will be within the spirit and scope of thepresent invention as is defined by the appended claims.

What I now claim is:

1. A ladder safety support device comprising a base member of U-shapedtubular construction, a U-shaped channel member carried by said baseproviding abutment means for legs of said ladder, a pivotable upright U-shaped tubular member carried by said base providing support means forsaid ladder, a pair of adjustable chains carried by said base and saidupright tubular member providing support for said device and hook meanscarried by said base for engagement with said chains for said device.

2. The combination according to claim 1, wherein, the

-shaped tubular member of said base of said device is secured at itsopen end within said U-shaped channel member of said base and saidU-shaped upright tubular member is secured at its open end to theinterior of the closed end of said base U-shaped tubular member by apair of bolts, thus allowing said upright member to fold downwards tosaid base of said device when said support device is not in use.

3. The combination according to claim 2, wherein, bolts extending fromsaid upright member are secured to one end of said chains and saidchains provide support means for said upright member when the lowerextremity of said chains are received upon hooks extending from the endwalls of said U-shaped channel member of said base.

4. The combination according to claim 3, wherein said base memberproviding said U-shaped channel member and said U-shaped tubular memberforms a frictional stop for the bottom of said ladder when said ladderis placed within the confines of said safety ladder support device andany tendency for said ladder to slip when weight is placed upwards andaway from the cross-bar portion supporting said ladder, said base memberprevents movement of the bottom of said ladder by said legs of saidladder being in engagement and abutment with said U-channel member andthe ground.
